报道了一种灿烂绿-聚氯乙烯膜涂层玻璃电极。该电极是将灿烂绿敏感的聚氯乙烯膜涂敷于pH玻璃电极表面而制得的。所制电极具有制作简单,使用方便和选择性良好等优点。其Nernst响应斜率为54.7mV/dec,响应线性范围为9.8×10-7~5.37×10-4mol/L的灿烂绿,能够直接用于灿烂绿的测定。将该电极应用于催化电位法分析,测定了环境水样中亚硝酸根的含量,结果满意。
A brilliant green-PVC film coated glass electrode was reported. The electrode is made of a brilliant green-sensitive polyvinyl chloride film coated on the surface of a pH glass electrode. The fabricated electrode has the advantages of simple manufacture, convenient use and good selectivity. The Nernst response slope of 54.7mV / dec and the linear response range of 9.8 × 10-7 ~ 5.37 × 10-4mol / L of brilliant green can be directly used for brilliant green determination. The electrode was applied to the catalytic potential analysis, determination of the content of nitrite in environmental water samples, with satisfactory results.
